The impact of surface coating on plasma ablation in magnetic anvil cells

ORAL

Abstract

Dielectric coatings have shown great promises in quenching plasma ablation, generated by the large current densities so commonly found in fast z-pinches. Once plasma ablation is reduced to a minimum, the current is constrained to only flow near conductors, giving exquisite control over the magnetic field. This control allows not only for more symmetric implosions, but also for more complex magnetic field typologies. We present here how different coating configurations impact the final pressure and homogeneity of warm dense matter samples using PERSEUS, an extended MHD code. Dropping the nonphysical vacuum resistivity, this code allows to study in great details how coating resistivity impacts the compression of the warm dense matter samples.
